What temperature rating are these? Could I use them on a 650W halogen fresnel? A: They melt on 250W tungstens. These aren't thick or high quality. S

The short answer is NO! I bought these to use with my landscape lighting as Christmas decoration and they began to melt immediately. I am using 75W halogen.

Good Morning Robyn,These lamps are halogen lamps which would get hot enough to melt or heat up oil. As long as the fixture has an approved rating for these kind of lamps then we would recommend it. If the it is not please know that some fixtures are made with consideration to heat tolerances particularly to the lamp operating temperature. Installing a lamp that operated at a high temperature than originally designed can be dangerous.

I would say yes, they give a nice light, better than the rather yellow CFL versions. I would have said it was more like 50W rather than a 40W equivalent. A nice light

It seems to be about that. I use mine for my porch light and it has been working in temps as low as 40 below. I have a 60w equivalent also and it seem about right too. This has the soft white color so it has the incandescent color.

Yes, but not as well as you might expect. Size and extra heat pose problems. So does quality when it comes to longevity. Their light pattern is not always as good as a stock bulb configuration. If you are after a brighter bulb using the stock wattage, use a Silverstar or PIAA . even if they burn a little hotter, their configuration prevents them from burning the socket or melting the lens.

Please note these are 12V bulbs, not 120V bulbs. That said, I have no way of measuring the color temperature of the bulbs but from my experience with others I'd say these are about 6000k.

I have not measured the heat output between the two bulbs and I have not had any heat problems. My guess on the heat would be the same or less. They are way brighter than the 24W bulb and I am happy with the light output.

I found on the internet that the +C may mean the bulb is coated to reduce heat to the fixture.. if that's the case then consider that these bulbs are only 3W, and produce very little heat.. make your own decision from there....

These cannot take ANY heat. I purchased them for my landscape lighting, 50 watt halogen, and they began to melt almost immediately. I'm not really sure what they ARE good for. Hope this helps.

Where did you see they were suitable for totally enclosed luminaries? I don't see that anywhere. The heatsinks on them get too hot to touch. These are my first LED bulbs, and from what I've read some get hot and some don't. So I don't know if that is going to affect them; being on all the time, or being totally enclosed. I don't see how the plastic globe part of them doesn't melt unless it's some kind of high-temp plastic.

I'm not sure. I use them for low voltage outdoor lights. I can say that the angle is fairly wide, so not 10 or 20 degrees.

I haven't noticed a wattage rating on the fixtures. 1000w is the high estimate of the tungsten equivalent of those 5 CFL's. The dual diffusers do cut the light output somewhat, but four of these units have been working for me for a couple of years. I suppose if you're a good electrician, you could change the fixtures. Sometimes, if I have a high white ceiling, I leave the softbox off of one of them, and just put it up high, pointed at the ceiling. I then use the others normally.

Anthony, I'm a bit slow on installing these, I bought 8 fixtures last year and another 2 recently. T8 fixtures are supposed to work well in low temperatures (20 F) so I'm trusting the liturature I read and what I've heard from coworkers enought to buy 10 of these fixtures. Sorry I don't yet have first hand experience.

Melted wow lol are you using the reccomended bulbs? I have two running 12hrs a day with uvb 5.0 fluorescent compacts bulbs (26W each) and no problem.

They should be fine below 30W. I use mine in an SVD V2 up to 20W with no issues.

In my experience the 130 volt bulbs would last longer since less voltage is heating the filaments to burn them out. They can be used in the US but may not burn as brightly at the lesser voltage. I doubt the you would even notice the variation with out a comparable voltage to determine the slight variation. I use the clear bulbs for more light over my vanities. Just be sure not to use 75 Watt enclosed in a fixture rated for lesser watts. The higher watts create more heat and could cause a fire unless the fixture is open to the air, or rated to use the higher wattage. Bert in Sebastopol, CA.

Dear Friend, Thanks for your message, you could buy the 1000W Fresnel light bulb(G22) and 650W Fresnel light bulb(GY9.5) for replacement. Have a nice day. best regards joey
